Be it known that I, ALBIN P. YSWAIIDMARK,

a citizen of the United States, residing at Hackensack, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Clamps for Hose, &c., of which the following is a specification.

Mi'y vention relates to clamps adapted to be c a mped around hose, pipe sections, etc., of varying diameter'and is an improvement upon the evices described in my Patent No.

1,219,882, hose clamp, dated March 20,.

1917. In the said atent is described a clamp which may be tted to hose of greatly varying diameters, the clamp comprising a metal ribbon which is wrapped around the hose or other object to be clamped in such a manner that adjustment may readily be made and the excess ribbon readily removed after the clamp has been installed. In the clamp described in said patent, a perpendicscored lines situated between the s lar or outwardly extending loopis formed in the ribbon. through openings in which a bolt may be extended, the portion of'the ribbon extending between the loop and the adjacent end of the ribbon being adapted to be overlapped by the other end portion of the ribbon which contains a lon 'tudinal'seriesof holes with one of whic the bolt extending through the loop may be alined. The nut of the bolt'is then screwed thereon to firmlyclamp the element or elements therein, after which the exoessribbon above'the nut may readily. be broken away, preferably along holes.

My present improvement has to do particularly with the portion of the ribbon extending between the loop and the adjacent end of the ribbon and the coaction of the samewith the underlying hose or other elemerit and the portion of the ribbon overlying the same, together with'the clamping .bolt and nut. I have found that drawing up the nut in the form of my invention just lgilelslpribed has a tendency to cause the hueg or wrinkling of the 'underlyin portion of the metal ribbon and of-the exible hose or the like clamped within the same,

this resulting in an imperfect jointibetween. the hose and thelpiilpe section or other ole-- ment clamped wit the same." I have now found, as the result of considerable experiment, that this defect may by directed to the accom I be overcome by providlng the portion of the metal ribbon, which extends from theloop to the adjacent end of the ribbon, with a lon'gitudinally extendlng bead or ridge. against which the 'overlymg portion of themetal ribbon is seated and firmly pressed when the nut is nut through the overlying portion of the metal ribbon 'will be taken up by the bead agamstwhich the overlying portion of the ribbon is pressed by the nut with the result that the underlying end portion of the ribbon will he firmly against the periphery of' the hose and be pressed with greater force agamst the same because of the bead, and neither the ribbon nor the hose will be wrinkled orbuckled to any degree what-- ever the clamping pressure exerted by the nut and bolt may be. In the preferred form of'my improved clamp, the portion of the ribbon extending from the loop to the adjacent end, which carries the bead or ridge I referred to, is provided with a preformed PAH O IC -1' p Patented Mal-.1, 1921.- Application filed May 27, 1918.

tightened on the clamping bolt. With th'rs constructlon, the pressure exerted by the my invention may be had, attention is hereforming part of this app 'cation and illus- 'trating certain embodiments of my invention. In the drawings, Figure 1 is an ex-' tended plan view of the preferred form of my clamp, Fig. 2 is a side elevation thereof,

Flg. 3 is a view of two of my clamps, viewed from opposite sides, joining two hose nying drawingslengths by means of a pipe section, Fig. 4

is a section taken on line 4-4 of Fig. 3,

' FigFf) is a cross-section taken on.line 5-5 ig. 2, and Fi -6 is a cross-section similarto Fig. 4, i ustrating' the manner in which two or more clamps may be joined {ogetfier in series to make a clamp of greater eferring to the drawings, the metal ribbon 5, which may be of steel, brass or any suitable equivalent, is bent into a rilerpendic ular loop 6 adjacent one end 7 of e ribbon, this-loop being punched or drilled to form a bearing for a bolt 8, provided with a nut 9, the latter being on the same side ofloop 6 as the end 7 of the ribbon. 1 q

The ribbon is rovided with a series of holes 10 spaced engthwise of the ribbon from the opposite end 11 thereof for a considerable portion of the length of the ribbon. The ribbon is also preferably provided with means for weakening the same between the holes 10, this weakening means preferably taking the form of lightly scored lines 12 formed transversely of the ribbon intermediate the holes 10, 10.

The end portion 13 of the ribbon extending from the loop 6 to the end 7 of the ribbon is provided with an outwardly extending longitudinal rib or head 14 whichis preferably located intermediate the side edges of the ribbon and is preferably formed by pressing the metal of the strip outwardly, as indicated in Fig. 5. The portion 13 of the ribbon is given an inward curvature, as

shown, at the same time-that the bead 14 is formed therein.

llVhen the clamp is to be in use, as is indicated in Figs. 3 and 4, the portion of the ribbon containing the holes 10 is laid over the forwardl extending portion 13 of the ribbon, the atter being provided with the outwardly extending bead 14. The ribbon is now bent outwardly in a direction more or less parallel to that of the loop 6, this bending being conveniently done along the scored line nearest to the loop when the ribbon has been so wrapped around the hose. The bolt 8 is now passed through the .hole 10 in line with the opening through loop 6, and the nut 9 screwed on the bolt. When the nut is tightened, the hose section 15 will be firmly clamped to the pipe section 16 or other element therein. The effect of screwing up nut 9 is to draw the overlying portion ofthe ribbon lengthwise over the bead 14 and at the same time to cause an inwardly directed pressure to be exerted by the overlying portion of the ribbon upon the head 14, which pressure is uniformly distributed by the portion 13 of the ribbon upon the hose within the same. The bead not only prevents the buckling of portion 13 of the ribbon, but also, because of the abutment which it forms for the overlying portion of the ribbon, causes the portion 13 to be pressed more tightly against the hose than would be possible if the bead were not used. It thus takes up any slack in the hose, tightens the same throughout its periphery, and prevents any buckling or wrinkling of the same.

After the nut 9 has been screwed up, the

excess ribbon may be broken 011' above nut 9, as is indlcated by the dotted lines in Figs. 3

and 4, this breaking away being readily ac complished along the scored line just above the nut, after the scorings are provided.

In Fig. 3, I have shown a hose section 17 clamped to a pipe section 16, upon the other.

end of which is clamped a hose section 15, a pair of clamping ribbons .5, 5 being used,

this being merely to illustrate one manner of using my clamp, and it will be seen that the clamp is easily and quickly attached and is applicable to varying diameters of hose.'

The manner in which a number of clamping ribbons may be joined together in series.

'5 through the end hole 10 of ribbon 5 adjacent to the end 11 of ribbon 5, ribbon 5 being bent outwardly along the scored line adjacent to the end hole 10 and nut 9 screwed into position as shown. The ribbon 5 then extends lengthwise of ribbon 5 over the end portion 13 of ribbon 5 and past the end? of ribbon 5, ribbon '5' being provided with a loop 6' beyond which extends its endportion 13'. The main portion of ribbon 5 may then be extended in the opposite direction around the hosel5', which is shown for purposes of illustration'as being clamped to the pipe section 16', the portion of ribbon 5 carrying its spaced holes 10 overlying the'end portion 13' of ribbon 5', bolt 8 of ribbon 5 being extended through the alined opening of rib bon 5, after which the excess length of ribternal ridge, said ribbon being provided with a series of-holes spaced longitudinally from its other end, and a bolt' adapted to. extend through the opening in said loop and, through the one of said holes alined therewith, when said ribbon is wrapped around a hose or the like with its portion provided with said holeslaid over the portion car ing said ridge and then bent outward y therefrom, and a nut for said bolt adapted to press the superposed portion of said ribbon firmly against saidridge, and to thereby press the portion of said ribbon carrying said ridge tightly against the inclosed hose.-

2. A clamp, comprising a metal ribbon adapted to be wrapped around a hoseor the like, having an outwardly extending loop formed adjacent one end, with an opening therethrough, with the portion between the loop and said end curved inwardly and having the metal thereof pressed outwardly to form a longitudinally extending central series of holes spaced longitudinally from its other end, and a bolt adapted to extend through the opening in said loop and through the one of said holes alined therewith, when said ribbon is wrapped around a hose or the like with its portion provided with said holes laid over the curved beaded portion, and then bent outwardly therefrom,

- and a nut for said bolt adapted to press the superposed portion of said ribbon firmly against said bead.

3. A clamp, comprising a metal ribbon adapted to be wrapped around a hose or the like, havingan outwardly extending loop formed adjacent one end, with an opening therethrough, with the portion between the loop and said end curved inwardly and provided with a longitudinal ridge, said ribbon being provided with a series of holes spaced longitudinally from its other end, and a bolt adapted to extend through the opening in said loop and through the a-lined one of said holes when said ribbon is wrapped around a hose or the like with its portion provided with said holes laid over the portion carryingrsaid ridge, and a nut for said bolt.
